Thanks! It's pretty silly, really, but it has been fun to play with. I only got switched to 'production mode' by Sincerely on Sunday, so I have yet to receive any of my test postcards - but their main business is printing people's photographs, so I think they should be fairly acceptable quality.

That's certainly a big a step in the right direction.

Art.sy launches to the public

According to the article it's "In the foreground, near the bottom of the image." I do see something near the bottom, halfway in the gap between the rover, that looks grey.... maybe metallic.
It was absolutely appreciated. I mentioned exactly that that in the article. But banning all references to an animal is straight crazy talk.
The story was posted 2 hours ago, do you think that might be enough time for them to have changed the nameservers back?

Luckily this was a test satellite with a planned short lifetime (from what I can understand).

They're going to use the propellant on the satellite to get as close as possible to their planned orbit, which would normally be more of a problem as it drastically shortens the lifetime of a LEO satellite which needs that propellant to keep altitude.
Moreover, I don't see what Firefox OS brings that Android cannot do...

Well, it has a decent WebView, for a start. It's damn near impossible to make a responsive webapp on Android, the WebView is awful. iOS isn't perfect, but is order of magnitudes better. Why Apple and not Google are pushing this, I have no idea. Google are supposed to be all about the web.
Ask HN - Are press releases worth the price?
I was looking at the cost of distributing press releases
http://www.businesswire.com/portal/site/home/submit-a-press-release/

Why are they so expensive? I mean, all they do is forward your press release to a bunch of publications, and some analytics? They charge 350$ per press release??

I've heard it from one of the karate instructors I've corresponded with (although in that context it was less of a dismissive phrase and more a cautionary one for our own training). Regardless of the origin, it's a good one.

That's just crazy. Whether or not cheaters should be exposed, I hope that mistakes bit is not your general policy for anything.
The ad-hoc thing is really nice for teams that seem to form spontanteously : Read as StartupWeekend, Hackathon, etc. But probably not for firmly established teams that have protocols and ways of working that are already formalized in project documentation and tools they've been using.

A todo list should definitely get out of your way (for the MOST part), but be intrusive enough that it helps you get the work done to be meaningfully differentiated. (just a personal opinion).

Keep trucking, I think this is a good tool for ad-hoc team task lists, and I'm sure you'll come up with some good use cases for that specific function.

And most importantly, don't let the nay-sayers get you down :-)

This means the Nazis with their V2 had been the first nation in space, which is why it's NOT generally accepted as we dont want this important part of our technologic development connected with them ..
I see one valuable thing in being able to instantly create a list and send it out to someone.
The point is that some people accepted they wouldn't do something, but they did. Rules broken = cheating.
Can you imagine a "smartphone" mobile platform without AAA game titles?

Absolutely. When the iPhone came out it had no AAA game titles- the major publishers held off until they saw what the market was like. I remember my first purchase (and addiction) being some sort of tank-shooting game that was little more than a glorified QBasic Gorillas.

Don't get me wrong, they'd need AAA games eventually, but everything has to start somewhere.
It's possible students (ignorantly) made their work public because they were proud of their accomplishments. I've done that once or twice under the assumption the course would change for other classes, if only slightly.

That being said, the onus is on the student to make sure they aren't submitting someone's work as their own. I'm not really sure if they understood what they were doing was serious (as in if Coursera was just a bunch of robot drones and they didn't give it much credibility). I know this incident legitimizes Coursera (and it's certificates of completion) in my eyes.

Really I believe all they need to say is, "Look, we really put a lot of work into this to make a good experience for people. We'd appreciate it if you took your answers offline and help make Coursera a respectable name in learning by submitting original work". The whole "We'll start expelling!" doesn't really strike a chord with me. I've been expelled before [not from coursera] for really dumb reasons.

# ALSO, they should take their Honor code out of the ToS. Put it somewhere that people READ!
I recognize you don't think it was unnecessarily negative, you're the one who posted it. I don't know that we needed that clarified.

What you mean here is "I don't think I would use this" - you don't have to tell him his idea is awesome, but the way you put it made it seem like you are the gatekeeper of awesome and this does not qualify, so go ahead start over and move on.

As OP made clear, he's scratching an itch and finds things like basecamp overcomplex. I agree, a trillion percent. We use Phabricator and it's great, but it took literally 3 days to get it all set up. If we were just starting out, I'd love to use something lightweight like this.
Thats what I have been using for this course. Bit bucket lets me have unlimited private repos. ( woot bitbucket )
Really, really hope this is a shard of a meteorite or something, not a piece of the rover's arm.
I agree with you, but that is mostly because I already have a 4 year degree in Engineering and I'm assuming you do too. There is a problem in the fact that many people cannot afford that degree because their parents can't afford it (or the loans that they'd need).

Cheating degrades the quality of education at any level. Cheaters are trying to get accreditation when they shouldn't. While Cheating is all over in education (we had a couple of cases at my school), it is obviously going to be more prominent in a place like Coursera, where cheating is easier and looking for cheaters is harder.

One thing they could do is create an algorithm that checks answers much like what they do for journals, but again that's an extra load they "shouldn't" have on their employees.
Assume some perfectly secure method of storing passwords existed. Attackers would be forced to shift to compromising them at the point of entry -- i.e. modify code or scrape memory to capture them at the point they are entered on the site.

An improvement (they have to be in motion, not at rest), but not a panacea. The problem is passwords... yeah, easy to state, hard to fix.

Here's hoping it's the Martian equivalent of an arrowhead. :-)

Or at least, let's hope it's not some critical piece of the rover itself.
Forget the certificate. If you enroll in a coursera course to learn, and you need some help getting started on the code or checking your work, why not take a look at the code? Not submitting it as your own, of course, but taking ownership of your education, which is all that matters.
Wow sorry about that, thanks for the correction. I'm going to defend myself by saying I'm at work and I just reply quickly between two tickets.

To be fair, the title of the post does say "startup" which implies the goal is to make money, and the poster asks for advice on revenue streams. If he had said, "Check out my weekend project, enjoy!" that's one thing, but calling the eleventy-billionth todo list app a startup is going to get replies like the OP.

Personally I agree in sentiment, if not in tone, with the OP; there's a trillion todo list apps, finding one the poster could have worked with would have freed valuable time for developing something else. Unless of course this was an app done for learning purposes, but the poster doesn't say that.
In my experience (and some benchmarking), there's no real difference in speed between using a Module-based factory method or using object prototypes. Modern JS engines optimize for both.
As a casual observer, I would think that it is just some bit of material that fell off of the rover.
I believe this is called "hustle".

It won't destroy all incentives to innovation. Hence the word 'monetary'. But if someone can make billions of dollars from innovating, that will certainly be a spur to do it, right?
I found this http://www.akkadia.org/drepper/cpumemory.pdf to be a very good starting point for getting into serious low level development. It's a difficult read, so go through it slowly and with a pad of paper for notes, but very information dense and useful.
"Whine" is an alert word for me. Any time someone tries to present his opponent's argument through an unflattering characterization "whining, stomping his feet, throwing a tantrum" rather than by presenting a well reasoned argument, I immediately become more guarded and skeptical about the argument I'm about to hear. Have you ever presented what you felt was a very fair and reasoned argument, only to have someone disregard it all and tell you you're whining?

I know, I know, you just can't expect too much from journalistic headlines. "Auto dealers claim that tesla stores are illegal" doesn't have the same punch. And based on what I've read here, I am on tesla's side (though it's pretty hard to find anyone on the side of the auto dealerships).
I really like this idea, to be honest. I think that ianpri makes some solid points but then again, it seems like this project isn't supposed to have those features.

I like that it does not require a login but a suggestion: have the user create a username for themselves that could tie them to the list. This would still make it so that nobody has to login, but yet you would be able to see who completed a certain task. Just an idea.

All in all I think it looks really nice, and I enjoyed the functionality and ease of making a list and letting others contribute to it. It literally takes a few seconds from landing on the site to have a functional list I can then send off to teammates.

Good stuff.

I know its not the elephant in the managed source code hosting space, but I like BitBucket better then Github. I like the option to use Mercerial for projects and I like the way they ask me to pay for things ( pay for private shared repositories ).
So the picture doesn't really make it obvious, but I believe they are talking about the item emphasized here[0]. I might just be dense, but why would NASA think that is a part of the rover, it really doesn't seem like it to me. As an aside, it also doesn't seem particularly "bright".

I think that's how I instantly analyzed the title: "how can someone cheat at coursera??". I get it that some people put the certifications on their resumes, but there are also a subset of people who take the courses just to learn, and therefore may not be able to spend the time doing the work.
For people searching for performance benchmarks like me, here are the numbers I dug around from the post (
http://geo.bitnames.com)

If you need less than 200 DNS lookups per second per DNS server the Perl version is fine and might be a little easier to setup. The Go version is much faster (in prodution we've seen it do 5-6000 requests a second on commodity hardware and even virtual servers).

Is 6000 rps a high number for a DNS server? Let me do a back of the envelope calculation: one simple dns request (assuming udp here) response msg size is 100bytes, 6000rps x 100bytes /1024/1024 x 8 = 4.69mbps. Even we consider the request msg size is equal to that of response msg, the throughput is still 9.38mbps, far from saturating the network pipe. It sounds to me there is still space for improvement.
If we go with the current train of thought around their seed? No.

But if they did create a new characteristic for that uterus, let's say it's resistive to disease, and that characteristic was passed down to the child. Then they would claim that child owed them money because that child's uterus benefits from the characteristic of the original uterus they provided.

The problem doesn't lay around the idea that Monsanto owns the seed they created. I don't dispute that. The problem is that they claim that they own the rights to anything resulting from that seed forever in the future, including cross pollination. Therefore, they feel fully justified in suing a farmer simply because his neighbor grows his crop from Monsanto seed and bees cross pollinated the crops.

The best defense I've heard against Monsanto is that Monsanto's seeds are contaminating "pure" or "natural" crops of soybeans. Which is probably where the argument that the seeds are indistinguishable from natural ones and resulting foods do not need a label telling the consumer the soybeans involved are genetically modified comes from. In that case Monsanto wants both sides covered to their advantage; ie, the seed is unique enough to allow for patent protection but no different than a natural one so you don't need to be told that it is genetically modified.
The fact that people publicly posting their work would get expelled disappoints me. During the Machine Learning class on Coursera, I did all of the programming exercises myself. After submitting the assignments and getting 100% scores, I would browse other people's GitHub repositories to see how they completed the assignment, which taught me more about both Octave syntax and machine learning and helped me to vectorize some of the more tricky algorithms (use Octave's native matrix operations rather than slower for loops).

The people who submit exact copies of assignments they find online should absolutely be penalized. To expel those who publish their work seems overly harsh.
When I notice a conversation veering into an unpleasant territory, I perk up, do the empathy-thing, and I naturally bring it back to something more pleasant.

I'm not comfortable with this as a general strategy stemming from a universal mantra. Learning this as an adult is impressive and probably exceptional, but it's a phenomenon we're all familiar with. We all know people who behave like this reflexively and have done so their entire adult lives. It can be pleasant to hang out with people like that in a heterogeneous group where not everyone is comfortable with everyone else, but they make damned unsatisfying friends and lovers. Policing comfort zones is a sure-fire intimacy killer, and it isn't exactly a triumph of empathy to avoid uncomfortable topics of conversation, even if it requires prodigious skill at empathy. Children of troubled and violent households, such as Bill Clinton, are the poster children for glib empathy that is a mile wide and an inch deep. (No political aspersions meant, by the way; I liked him as a politician and a president.)

I would argue that in this case we are seeing a misguided (and probably temporary) "zeal of the convert", and by convert I mean someone who has discovered the practical value of this Clintonesque "emotional easing." Emotional easing is much like quantitative easing: it shifts unpleasantness out of the current context. It's a valuable tool, but it can't be applied universally. I'm not comfortable calling it empathy, either. "Perking up" when another person's uncomfortable emotions come to the fore and steering the conversation away teaches them that their problems are their own, and that their full selves are excluded while a partial self (with unpleasantness filtered out) is welcome. That's appropriate in some social contexts, but not all, not by a long shot, just like quantitative easing is only appropriate in certain contexts. And it's the opposite of empathy, even though executing it requires a limited use of empathy. Empathy means feeling what another person is feeling because your human bonds transcend the difference between you, not strategically tapping into their problematic feelings so you can override them with your own more attractive and pleasant ones.
To me, this is a blog post chock full of anecdotal evidence to support a determined, central, dare I say biased, thesis. I find it continually amazing that people don't see this, from simple blog posts like this one, to now-famous books like "Good To Great" and other airport middle-management best-sellers.

Not that anything is wrong with that. Obviously, if you are interested in other people's opinion in this domain, it's likely you feel you are doing something wrong. And, trying different methods can jog whatever dynamic you are in that you feel doesn't work.

But, it's a big step from that to some of the opinions-as-fact (and eventually into "methodologies", "movements" and "manifestos") that sprout from such starting points.

I don't think anyone has the one magic bullet for "best. management style. evar."
Smoking Apache Lucene with Redis (experimental Solr Support)
I disagree with your assertion. Cheating is not necessarily an act of malice. As an example, a friend of mine (who is from India) helped another student (also Indian) with a programming project in an intro to CS class at my alma mater. My friend was trying to help a friend out, not intentionally trying to break the rules. This took place during the first few weeks of school, mind you, and neither student had any significant experience with the ethical standards of American institutions. Both students readily admitted to what had happened- neither was trying to hide anything. Nonetheless, the professor gave my friend a two letter grade demotion and the person whom he helped an F. Arguments about the fairness of their punishments aside, I don't think it's fair to assert that either had a lapse in ethical judgement more than a cultural misunderstanding, but nonetheless both students did cheat.
Thank you so much, @yakshaving!

I hadn't thought about StartupWeekend, and Hackathon, actually. Any ideas on how I might reach them to see if they could somehow encourage teams to use this?!

Naming Things with Hashes
But is someone telling you their exact feelings at that moment really honesty? If everyone were completely honest with each other, the world would be a vastly different place.

Let's say you invite a co-worker out to lunch. He doesn't like you. He could either say, "I don't like you," or "I'm busy."

In your world, he would be straightforward about his feelings and tell you he doesn't like you. This kind of communication injures egos and causes hostility and friction. It makes for an unpleasant work environment.

Instead when he says, "I'm busy," you don't know if he was really busy or he doesn't like you. He may even say, "I'd love to go out to lunch with you, but I'm busy. So sorry. Let's do it another time."

So you ask him again the next day. He's busy again. You ask him again the day after. Still busy. He never asks you out to lunch and never makes an effort with you.

Now what you have here is a truly honest signal. His actions are an honest signal. His words are bullshit. Everyone's words are bullshit. People will lie to themselves under social pressure and act like they are interested. But a person's actions don't lie.

Bcrypt is a key lengthening algorithm for individual passwords. This article talks about a method that divides a password into pieces to store on physically different machines, that may reside in different parts of the world.

I can see bcrypt and distributed credential protection complementing each other to form a rather robust security policy. But then again, I'm not a security expert.
I would think it would be better to let the course go on, and mail the certificates and give each one a unique identifier. Then make an annotation at cousera of which students were caught cheating. Then give employers the ability to check if a certificate is from an honest student or one who was caught cheating. Everyone wins.
I wonder if the hard drive manufacturers will reconsider locating their entire supply chain in a third world country with frequent natural disasters after this incident.

We have built this website at Startup Weekend event and I want your feedback for both the idea and the site for further development. Thanks in advance! You are awesome :)
It wouldn't be useless but it could be unnecessary. I don't anticipate ever needing to set up version control, unless it's my own business. Any place I work will almost certain already have it set up, and if not, someone else will be tasked to set it up.
I'm having trouble thinking of reasons why bitbucket is used so much less than github - or at least why it seems that way.

It's looking pretty damn good to me right now!
